Previous studies indicate that the southward migration through Oregon lasts about two months (Herzing and Mate 1984). However, 90% of the whales migrated past Yaquina Head between December 19 and January 23. The northward migration through Oregon is divided in two phases. Phase A, which comprises adults without calves, begins during the last week of February with a peak in mid-March.
Though orcas, humpbacks, and belugas are the most frequently seen large cetaceans in Alaska, many other species spend at least part of the year in Alaskan waters. Gray whales migrating from Baja California pass along the outer coast of Southeast Alaska on the way to summer feeding grounds in the Bering Sea. In addition to viewing opportunities during migration, some individuals occasionally remain along Southeast Alaska's outer coast for the summer.
